Which statement about conductivity and temperature is correct?

• A. Conductivity Increases With Temperature.
• B. Conductivity Decreases With Temperature.
• C. Conductivity Is Independent Of Temperature.
• D. Conductivity Varies Randomly With Temperature.

Answer: (A)

Conductivity in liquids and electrolyte solutions generally rises as temperature increases. Higher temperature makes the solvent less viscous and gives ions more kinetic energy, so they move and diffuse more quickly under an electric field. This increased ion mobility translates to a greater charge transport per unit area, boosting conductivity. Temperature can also raise solubility for some solutes, adding more charge carriers. So the statement that conductivity increases with temperature best matches how most electrolytes behave. (Note: metals often show the opposite trend because electron scattering increases with temperature, but that’s a different context.)
